Hello all. I'm changing out heads. Bought the car with a 383 in it, it's a 74. I have no info on the build, so I'm getting an idea now. I know you can't be exact fro pictures, but any idea on cc of pistons? Looks like compression was less than I thought. had 75cc gm heads. Got a good deal on world torquers, 67cc.
Thanks for the help. brent
Also .040 is stamped on the piston
The engine in my build has 6" rods and the pistons are dished. The heads I'm using are 64cc to acquire a C/R of 10.5 to one. Don't know the build of your engine or if they used 6' rods in 383 builds. T
piston size
